How to create a SmartArt ornigazation chart into PowerPoint programmatically?

[ty05]

Hi all,

I need to add function in the application that allow users to download their organization chart as SmartArt organization chart in PPT.

I tried with Python library, but it does not create the org chart as SmartArt.

It does not have to be Python, but could anyone please help and share sample codes?
I found the doc below, but I am not familer with C# and not sure if it works or not.

Never mind. I found a sample code in Java.
